The functions to fetch e-mail via POP3 or IMAP as well as sending e-mail via SMTP use OpenSSL for static SSL or TLS based communication. As the SSLgetverifyresult() function is not used the certificated is trusted always and it can not be ensured that the certificate satisfies all necessary security requirements.

This could allow an attacker to use an invalid certificate to claim to be a trusted host, use expired certificates, or conduct other attacks that could be detected if the certificate is properly validated.

Attacker might be able to execute malicious Perl code in the Template toolkit, by having the admin installing an unverified 3th party package

OTRS Community Edition contains an authenticated OS command injection vulnerability in the PGP encryption module that allows administrators to execute arbitrary operating-system commands by supplying crafted values for the PGP binary path and command options. Administrator-supplied configuration values are concatenated without sanitization into a shell command, enabling arbitrary command execution as the web server process user during normal ticket operations after the malicious configuration is deployed.

Passwords of agents and customers are displayed in plain text in the OTRS admin log module if certain configurations regarding the authentication sources match and debugging for the authentication backend has been enabled.
